WINDOW-SCREEN.

SPECIFICATION forming To all whom it may cortcern:

Be it known that 1,. Lines Warson, a citizen of the United'States, residing at Mari- -nette, in the county of Marinette and State of Wisconsin, have'invented anew and useful Window-Screen, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to window-screens, and its object is to provide ascreen possessing superior advantages in point of simplicity, convenience, durability, and general efficiency.

In the drawings, Figure 1 is a front elevation of a window-frame embodying my improvements. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a vertitical longitudinal sectional view, showing the sashes in different position. Fig. 4 is a hori zontal sectional view on the line at m, Fig. 3.

' Referring to the drawings, A designates the window frame or casing, which may be in the main of any ordinary or suitable construction, it being provided with the usual longitudinal guide-grooves, B B, in the inner faces of its side pieces, 6 C, for the sashes, and with a transverse slot, D, in its top piece, E, and sill F, as shown.

G is the upper sash, and H the lower'sash,

these being adapted to slide vertically in the grooves BB and through the slots D D. The frames I of these sashes G and H are somewhat longer than half thelength of the casing A,

and are divided by a cross-strip, J, into two portions, the main portionbeing provided with.

.the windowglass K, andv adapted to close half the window-opening when the sash is in nor mal position, while the remaining portion is provided with a screen, L, that will be down in the slot D and out of sight, and the crossstrip J will close the slotopening 1) when the sash is in its normal closed position. When desired, one or both of the sashes can be slid in the grooves 13 B to expose the screen portion L, (this positionbeing shown in full lines Fig. 3 of the drawings) when a free circula tion of air will be secured through the screen,

while the latter will bar' the entrance of flies,

insects, and the like. When it becomes desirable to throw open the sash, either one can be still further slid to the position shown in dotted lines, Fig. 3, when the screen portion will be entirely free from the slot D, as shown.

part of Letters Patent 310,288,282, dated November 1?, 1883.

Application filed June 14, 1883. (No model.) i

l The cross-pieces J J of the sashes are prefer,

ably provided with laterally-projecting ribs or stripsM, having strips of elastic material N on their engaging-edges; or any other suitable weather-strip can be used which will come against the end pieces, E and F, of the casing A when the sashes are closed. The strips M M. will also serve as stops to limit the move-' ment of the sashes into the slots D D when they are being closed into normal position. The inner end pieces of the frames of the sashes are also preferably provided with inweirdly-projecting strips or flanges O, which come together when the sashes are in normal position to provide a weather-strip at this joint. The under edge of the end strip of the upper sash may also be provided with an inwardly-proj ecting strip, (not shown,) that will serve to close the open place between the sashes when either one of the latter is partially open. a V

The operation and advantages of my inven-' tion will be readily understood and appreciated. It is very simple and inexpensive in construction, and by having the screen a part of the sash all trouble of adjusting the same is obviated, and displacement or loss is avoided. 8

I claim as my invention- As an improvement in window-screens, the

its frame an end cross-strip, J, which carries a screen portion, L, and is provided with a lateral longitudinal strip, M, which strips M M come against the sill and toppiece of the window-casing to limit movement of their re- 9 spective sashes, and also provided with an inner end strip that is formed with an inwardlyprojecting longitudinal flange, 0, which engages with the corresponding flange O on the other sash, and also with the st-rips'M M, and a weather-strip, N, secured to the .contactedges of strips M M, all arranged and operating as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in 106 presence of two witnesses.

JAMES WATSON.
